Vedclass · Answer

(A) In a hydroxyl ion,$OH^{\ominus}$,the oxygen atom has $6$ valence electrons. It shares $1$ electron with the hydrogen atom to form a covalent bond,and it gains $1$ electron due to the negative charge. This results in $8$ electrons around the oxygen atom,which corresponds to $4$ electron pairs. Out of these $4$ pairs,$1$ pair is involved in the $O-H$ covalent bond,and the remaining $3$ pairs are lone pairs on the oxygen atom.

Column $I$ (Molecules)	Column $II$ (Number of lone pairs on central atom)
$A. \ NH_3$	$1. \ \text{Two}$
$B. \ H_2O$	$2. \ \text{Three}$
$C. \ XeF_2$	$3. \ \text{Zero}$
$D. \ CH_4$	$4. \ \text{Four}$
	$5. \ \text{One}$
